Ssesses the lowest cost of feedstock. The study also concluded that when the fermentation residues had been applied to create power through a cogeneration system, MESPs may be reduced by as much as 17 . Demichelis et al. (2020) [82] assessed the price advantage of co-production of bioethanol and biogas from different substrates. As anticipated, working with sugar-based components (sugarcane) is much more lucrative than applying lignocellulosic biomass (rice straw), resulting in 89.four and 50.3 decrease NPV and ROI of ethanol production from rice straw than from sugarcane, respectively.Table 3.

Da Silva et al. (2016) [98] discovered that the distinction in energy made use of in diverse pretreatment processes, liquid hot water (LHW) and ammonia fiber explosion (AFEX), brought on varying MESPs, ranging from USD 1.78.47/L. Similarly, Zang (2020) [99] indicated that, in the co-production of ethanol, furfural, and lignin from switchgrass, the pretreatment (fractionation) price accounted for 35.five with the total production, becoming probably the most pricey step, followed by feedstock price as the second most pricey. Efforts to cut down the MESP of 2G ethanol, allowing it to be competitive with 1G ethanol, have already been demonstrated in many studies on the production of ethanol alone. Therein, incinerating high lignin content solid residues resulted within a certain volume of power that might be supplemental to the key procedure. Nonetheless, it seems that relying on strong residues alone may not be adequate to cut down the MESP of 2G ethanol for the desired level. These added solutions came in two forms, like (1) energy and fuel toFermentation 2021, 7,17 ofsupplement the principle procedure.
